The endsof the first, second and intermediate plates having channels. Theintermediate plate is inverted relative to the first and second platesand the channels in the intermediate plate receives the lower edges ofthe girders mounting said first plate.

The present invention relates to the cooling of liquids where theliquids are allowed to run along or stream upon cooling surfaces. Theinvention is particularly concerned with plate assemblies for liquidcooling installations.

United States Patent No. 2,836,405, dated May 27, 1958 discloses andclaims a plate assembly for liquid cooling installations comprising aplurality of horizontally extending substantially flat plates grouped insuperposed and spaced relation in each of several vertical parallelplanes; adjacent plates in said vertical planes forming horizontal rows;stationary supports freely engaging the ends of the plates of each rowto hold the plates in suspended position; distancing connectorsextending perpendicularly to said planes between each pair of an upperand a lower row of plates; an upper and a lower series of spacedvertical slots in each connector, said slots adapted to receive theborder portions of the plates of said upper and lower rows respectively;the border portions of the plates of each upper row resting loosely intheir respective slots having a width exceeding the thickness of saidborder portions and the border portion of the plates of each lower rowbeing frictionally held in their respective slots having a widthsubstantially equal to the thickness of said border portions.

The object of the present invention, is to provide a plate assembly forliquid cooling installations, the assembly comprising:

(i) A first liquid trickling plate;

(ii) A second liquid trickling plate mounted beneath said first plate;

(iii) Mounting means for supporting said first and said first plate;

(iv) An intermediate trickling plate interposed between said first andsecond plates and supported by said second plate; and

(v) Connecting means connecting said intermediate plate to said firstand second plates.

The intermediate liquid trickling plate may be formed of a substantiallyrectangular plate which preferably has a width corresponding to that ofeither of the other trickling plates supported by the mounting means.When it is necessary, because of their span, for the mounting means,which may be in the form of girders, to have a height such that thelower face thereof extends lower than the upper edge of the intermediateplate, the intermediate plate is channelled at its upper corners. Thesechannels may be adapted in shape to the projection of the mountingmeans, but the intermediate plate is preferably formed by one of theliquid trickling plates supported by the mounting means, the position ofwhich has been reversed so that its upper edge now becomes its loweredge. Thus, groups of liquid trickling plates may be formed by theutilisation of a single shape of liquid trickling plate, this being anadvantage which justifies the use of this arrangement also in the caseswhere the lower faces of the mounting means do not extend to a lowerdepth than the upper edge of the intermediate plates.

For a better understanding of the invention, and to show how the samemay be carried into effect, reference will now be made, by way ofexample, to the accompanying drawings, in which:

The figure is a front elevation, partly in section of the presentinvention.

In the drawings, there is shown a plate assembly for liquid coolinginstallations. In the assembly, liquid trickling elements 2', in theform of plates, are interposed between trickling elements 2, also in theform of plates which are supported laterally by girders 3 formingmounting means for mounting the elements 2. The trickling elements 2 aremounted on and supported by the lower elements 2 by the connectionprovided by connecting members 5'. The connecting members 5 connect theupper edges of the trickling eleemnts 2 to the lower edges of the upperelements 2.

The interposed trickling elements 2 may be formed by rectangular plates,the width of which corresponds to the width of the elements 2.

I claim:

1. A plate assembly for liquid cooling installations comprising:

a first liquid trickling plate disposed in a vertical plane;

a second liquid trickling plate disposed in said vertical plane beneathsaid first plate, each of said first and second plates having adownwardly facing shoulder portion at each end formed by a channel; anintermediate trickling plate disposed in said vertical plane betweensaid first and second plates;

stationary mounting means engaging the ends of and supporting said firstand second plates, said mounting means being independent of saidintermediate plate and including first and second pairs of horizontalgirders extending transversely of said vertical plane, the shoulders ofsaid first plate resting on said first pair of girders and the shoulderson said second plate resting on said second pair of girders, the loweredges of said first pair of girders extending lower than the upper edgeof said intermediate plate, and the ends of said intermediate platebeing channelled similarly to the ends of said first and second plates,said intermediate plate being inverted relative to said first and secondplates and the channels in said intermediate plates receiving the loweredges of said first pair of girders;
